EQ1979 Analog Strip and EQ
EQ1979 is a frequency accurate modeling of a Neve 1073 filter stage combined with an input gain-compensated saturation.
- Designed by cascading ~40 peq/butterworth filters to reproduce frequency response, bumps and drops of the original console strip, - Neve-inspired GUI with big knobs and that slick Neve soft blue background. - Input saturation based on brute “arctan” sat which is gain-compensated. - Includes additional independant gain trimming.
Controls : - Saturation: Left mouse button to change Saturation value, Wheel to change makeup gain, right mouse to reset either Sat or makeup - Frequency bands : Left to change filter gain, wheel swaps frequency bands. Right mouse button resets these as well.

Versions : - Beta 0.95
- Improved modeling of HPF and Low Shelf filter responses
- 10Hz parameter smoothing on Low, Mid and High frequency gain parameters for automation-safe operation
- Beta 0.94 - internal bugfixing stage never released - Beta 0.93
- HPF frequency response tuned with expected bump
- Testing parameter smoothing on HPF
- Correcting minor GUI bugs on switching to +-16dB for shelfs
- Beta 0.92 :
- GUI : Added mousex lock on control change, no more control swapping when adjusting parameter
- Lowered low and high shelf EQ max gain down to 16dB as per original 1073 design
- Added EQ On/Off and Phase buttons as per original 1073 design
- minor tweaks
- Beta 0.91 - Low Shelf GUI Fix and Sat mouse speed increase by 25% - Beta 0.9 - First release
This was developped by analysing datasheet and pulling out in a retry-on error fashion an “equivalent” frequency response. This using both plugindoctor and ear tests VS the latest UAD 1073 emulation plugin. Filter methods are derived from Oliver Belanger's COOKDSP library - Copyright © - 2014 - Olivier Belanger
Here are some of the final comparison diagrams, orange/blue curves are UAD Neve 1073 native plugin L/R channel, pink is EQ1979:
Raw static with mid engaged (with typical 1073 mid bump)
Typical Neve “Air” 14dB high boost (with its mid drop)
Typical Neve Mid “front push” 14dB 1.6k boost
To Do : - Implement parameter smoothing to avoid glitches during automation, - Low shelf filter bumps - BLower high pass input filter to ear accurate model
